Embodiment
Below describe the embodiments of the present invention in detail.Although concrete execution mode has been discussed, should be understood that, this is only for illustrative purposes.In the situation that not deviating from the spirit and scope of the invention, person of skill in the art will appreciate that and can use other assembly and configuration.
In data center network, provide lossless operation to depend on effective management of wrapping buffering area.This bag cache management is for guaranteeing that Bao Buhui is because congested abandoning is crucial.A feature of the present invention is the flow-control mechanism that can use based on byte.In one embodiment, the transmitter of buffer status of the flow-control mechanism based on byte based on effectively maintaining receiver place.Maintaining in the buffer status at receiver place, transmitter provides the information relevant with byte expansion at receiver place.The amount of the needed extra storage of receiver when this byte expansion information can be used to determine the bag that storage is transmitted by transmitter in the bag buffering area of receiver by transmitter.
Transmit explicitly with the bag of transmitter, transmitter is configured to determine the adjustment at the buffer status at receiver place by byte expansion information.In one embodiment, determined adjustment is for being adjusted at the prestige counter at transmitter place, and this prestige counter reflects the level of filling of the bag buffering area of receiver.In the time having free space in the readings signify of the prestige counter of the transmitter bag buffering area at receiver, transmission package and use the byte size of transmitted bag to add that the extra byte number of being indicated by byte expansion information adjusts prestige counter.Because the real bytes that byte expansion information makes transmitter can maintain the bag buffering area place of receiver is counted, so can remove the consideration of surplus.Thereby improve the efficiency of bag buffer management.
Providing in harmless performance, transmitter and receiver are configured to cooperation can be held by the bag buffering area at receiver place with whole bags of guaranteeing to be sent by transmitter.In the flow control scheme based on preferential such as defining in IEEE802.1Qbb, this performance depends on the surplus of the assurance of wrapping buffering area.
Fig. 1 shows the required surplus in the bag buffering area using in the flow control scheme based on preferential.In the flow control scheme based on preferential, the value of 2 bytes that the time-out duration of all kinds of services is is quantum number by time representation, wherein each quantum representative is transmitted the required time of 512 bits under current network speed.In this framework, use the receiver of the current control based on preferential to be configured to estimate that the potential buffering area of a class service consumes, and produce the pause frame for such service in the time that this situation occurs.Then, pause frame is transferred to transmitter, and before making the bag buffer overflow in receiver, the time that transmitter has q.s stops transmission.
Fig. 1 shows the amount of required surplus.The amount of this surplus be shown as roughly corresponding to receiver by send pause frame to transmitter to stop the untapped bag buffer level of transmission (XOFF).As shown, the transmission of pause frame does not stop bag buffering area to continue to fill immediately.This is because time quantum (TX time) and transmitter that pause frame spends through link are being processed the time quantum (response time) that stops the pause frame of further bag transmission to spend to a great extent.
Here the effect length receiver that should note link, must take action to prevent that buffering area is full of and packet loss in how early.Link is longer, and receiver should more early send pause frame to transmitter.Usually, the various considerations of the transmission in the flow control scheme based on preferential and processing delay must be considered the worst case of buffering area.The result that adapts to these worst cases is exactly the rare buffer resource of the more substantial bag of needs buffering area.
Should be understood that buffer size also depends on link-speeds.Link-speeds is faster, and the amount of required surplus is larger.For example, consideration link-speeds is brought up to 40GbE or is brought up to 100GbE from 10GbE from 10GbE.Because the restriction of the flow control scheme based on preferential is emphasized, the raising of this link-speeds can cause the very big demand (for example, hundreds of kilobytes) to surplus buffering area demand.The impact obtaining is the restriction for the number of the harmless service type that can enable on link.This restriction can have the appreciable impact on service quality.In addition, should notice that the total amount of surplus of each device and the port number of this device support are proportional.In the time of the higher port density of hope, wish that the efficiency of bag Buffer allocation is higher.
Therefore, feature of the present invention be to provide based on byte rather than such as the time-based novel flow-control mechanism being exemplified by the flow control scheme based on preferential.Conventionally, wish novel flow-control mechanism to bag how, automatic synchronization insensitive in the storage of receiver place, surplus is low and can use asymmetrically at each link direction.
Fig. 2 shows the example embodiment for the effective flow-control mechanism based on prestige on the link between transmitter 210 and receiver 220.At this, transmitter 210 and receiver 220 can represent switch, server, network interface unit (NIC) or any other network equipment of can be used as link partner.Be included in receiver 220 be bag buffering area 222, it can have size Bi to process the transmission " i " of specific harmless classification.
As directed, transmitter 210 comprises prestige counter 212, and it makes transmitter 210 can effectively maintain with the form of prestige the state of the bag buffering area 222 in receiver 220.Of the present invention be characterized as by transmitter 210 maintain the state of the bag buffering area 222 in receiver 220 eliminating solve bag worst case arrive needs.As the following more detailed description, prestige counting is transferred to transmitter 210 from receiver 220 and is counted together with maintaining real bytes the needs of having eliminated a large amount of surpluses shown in the flow control scheme based on preferential.
At this, should notice that byte prestige is in theory conventionally more accurate than bag prestige.But owing to having the byte expansion at receiver place of buffering area of the granularity for example, than byte (, row or page) larger for storing metadata and management, byte prestige technology is problematic.In the present invention, at transmitter place, byte prestige current control is added with byte expansion function f (bag size), the byte expansion that its representative is carried out at receiver place.At this, the actual amount of the buffer stores being used by receiver in the time storing the bag of the given bag size receiving from transmitter in the byte expansion representative at receiver place.Know the byte expansion of being carried out by receiver, transmitter can be processed the store status in the bag buffering area at receiver place now exactly.Therefore, along with bag is transferred to receiver by transmitter, transmitter can upgrade prestige counter with byte expansion function, to maintain and to follow the trail of the real use state of the bag buffering area in receiver.
By maintaining the state of the bag buffering area in receiver, transmitter can be made bag and whether can be sent to the judgement of receiver.As shown in Figure 2, whether transmitter 210 can be configured to realize and indicate the byte expansion of bag to be sent can be contained in the judgement 214 in the free space in the bag buffering area 222 in transmitter 220 for prestige counter.Should be understood that and judge that 214 can be undertaken by machine code and/or computer program, thereby this machine code and/or computer program have and can be carried out and be made machine and/or computer carry out at least one code segment of this judgement by machine and/or computer.
If judge that 214 indication byte expanding packet can be stored in the free space in bag buffering area 222, bag is sent to receiver 220 by transmitter 210 so.Then, receiver can store extended byte bag in bag buffering area 222.With bag is sent to receiver 220 explicitly, the byte expansion function based on being applied to the bag having sent is adjusted prestige counter 212.
At this, should notice that adjusting prestige counting 212 with the byte expansion function that is applied to transmitted bag is intended to reflect the minimizing of wrapping the free memory in buffering area 222.When byte expansion function f (bag) is by transmitter 210 priori when known, transmitter 210 can maintain the state of the bag buffering area 222 in receiver 220 effectively.Therefore, compared with the possibility of the worst case of the byte on distribution, the transmission of being undertaken by transmitter 210 can be after the actual transmissions byte solving on distribution time-out.
Fig. 3 shows the buffering area example of the current control of use according to the present invention based on prestige.As shown, determine the size of prestige threshold value with reflection bag buffering area.In the time that bag is transferred to receiver from transmitter, bag buffering area can continue to fill.Prestige counter 212 will be continued to adjust the minimizing in the available part to be reflected in bag buffering area 222 based on byte expansion function f (bag).Based on judging 214, transmitter 210 sends bag by continuing until prestige counter 212 indicates byte expanding packet can not be contained in the available part of residue of bag buffering area 222.At this, should note the judgement 214 of the further time-out transmitting based on using prestige counter 214 to carry out, rather than receive the pause frame from receiver 220.
In the example of Fig. 3, further the time-out of transmission is shown in when prestige counter indicates the byte expansion of next bag waiting for transmission can not be contained in the available part of residue of wrapping buffering area and occurs.Because the size that this suspends based on bag, is for example shown as, with MTU (MTU) size (, 1.5 kilobytes, 2 kilobytes, 9.6 kilobytes etc.) similar so suspend generable level.Should be understood that with the relative little amount being associated of MTU size and relate to real bytes counting, and much smaller than hundreds of bytes of the surplus that can be associated with transmission and response time.
As long as prestige counter 212 indicates byte expanding packet can not be contained in the available part of residue of bag buffering area 222, transmitter 210 just can not transmit any bag.This situation will keep until emptying in receiver 220 bag buffering areas 222, place.The message of the renewal of the byte that in the present invention, reflection is discharged from bag buffering area 222 based on send to transmitter 210 from receiver 220.In one embodiment, updating message can be according to using mac frame with the similar mode of flow control scheme based on preferential.
In one embodiment, the prestige counter 212 in transmitter 210 is cycle counters.This cycle counter can have identical bit number with the cycle counter in receiver.Can increase the expansion of the byte that is applied to transmission at the cycle counter at transmitter place, and can increase at the cycle counter at receiver place the extended byte being stored in bag buffering area.In one embodiment, transmitter can be configured to regularly send the sync packet that is included in the value that sends sync packet hour counter, and receiver can send the renewal of returning to its cycle counter and add the value of available buffer in the time receiving this sync packet.Conventionally,, because system will be upgraded recovery at next, the loss that prestige is upgraded is harmless.Therefore, because it can upgrade recovery loss from packet loss and prestige, so provide self synchronous.
Described the framework for the current control based on prestige, the flow chart that refers now to Fig. 4 illustrates processing of the present invention.As shown in the figure, this processing starts from receiving from link partner the step 402 of byte expansion information.It should be noted that the flow-control mechanism based on prestige can asymmetric operation on link.Correspondingly, the processing of step 402 can be a part for the extensive exchange of the flow-control capability information between link partner.
In one embodiment, exchange (DCBX) agreement by data center bridging and can promote capabilities exchange.In one embodiment, DCBX agreement can and exchange the flow control information based on prestige for bulletin.In various situations, link partner can be announces their supports to the control information based on prestige stream, confer the bit number in prestige counter, the information of the byte expansion from receiver to transmitter is provided, maybe will make it possible to carry out any out of Memory of the control operation based on prestige stream.
Using after current control based on prestige sets up the link of at least one direction, prestige counter can be monitored the state with respect to the bag buffering area of the receiver of the prestige threshold value of setting up subsequently.At run duration, transmitter can determine in step 404 whether prestige counter indicates the bag buffering area of receiver to have the space that holds byte expansion bag subsequently.By byte expansion information is provided to transmitter by receiver and promotes this judgement before.
If determine the space that the bag buffering area of prestige counter indication receiver does not hold byte expansion bag in step 404, this processing will loop back the further inspection of prestige counter subsequently so.As described in reference to Figure 3, the indication that prestige counter can be based on being provided by receiver is the prestige of the emptying byte adjustment of more newly arriving from bag buffering area.At this, although it should be noted that concrete prestige update mechanism relies on realization, the prestige of receiver is upgraded interval can affect the throughput in system.
If determine that in step 404 there is the space that holds byte expansion bag the bag buffering area of prestige counter indication receiver, thereby in step 406, bag is transferred to the bag buffering area that receiver is stored in receiver from transmitter so.Subsequently, in step 408, the byte expansion amount of the bag based on transmitted is adjusted prestige counter, and this byte expansion amount is determined by the byte expansion information previously receiving.Adjustment at the prestige counter at transmitter place makes transmitter can maintain the state of the bag buffering area of receiver.Subsequently, at run duration, this processing will loop back step 404 further to check prestige counter.
It should be noted that step order in the flow chart of Fig. 4 is only for the object of explanation provides.In reality realizes, some steps can be carried out simultaneously or with alternative order.Only in the case of the operation of particular step strictly depend on the input being produced by another step just can be between any two steps appointment order.
As has been described, the flow-control mechanism based on prestige can guarantee harmless behavior and not need obvious surplus with reply linkage length, processing delay etc.Conventionally, harmless performance be can guarantee and prestige threshold level, bag size, transmission mode, propagation delay etc. do not considered.Compared with current control based on preferential, under lossless mode, can realize higher throughput for given buffering capacity, or buffering capacity that need to be lower under harmless link is to realize given throughput.
Another embodiment of the present invention can provide the machine and/or computer-readable memory and/or the medium that on it, store machine code and/or computer program, thereby this machine code and/or computer program have and can be carried out and be made machine and/or computer carry out at least one code segment of step as described in this article by machine and/or computer.
These and other aspect of the present invention will become apparent for those skilled in the art by the embodiment before looking back.Although many notable features of the present invention are in above description, but, the present invention can have other execution mode and can be with reading after disclosed invention the apparent variety of way practice of those skilled in the art and realization, and therefore above description should not be considered to get rid of these other execution modes.Equally, be to be understood that herein the word that adopts and term are that object in order to describe should not be considered to restriction.
